Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterHeatShield Chimney Liner & Rebuild in Littleton: What to Know First
We provide independent HeatShield chimney liner and rebuild service in Littleton, typically scheduling within 3-5 business days and completing most liner replacements in a single day. Every job starts with a written price before work begins - no exceptions, no surprises. If you own a HeatShield flue liner or factory-built chimney system and you’re seeing staining, draft problems, or a failed inspection, this page covers what actually fails, what it costs, and how we document the fix. Call (720) 439-4666 for a free estimate.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Flue Sealant (joint repair system) - delamination in freeze-thaw cycles. The Cerfractory coating is designed to resurface clay flue tiles, but in Littleton’s climate, the 30-40 degree daily temperature swings through fall and spring stress the bond layer. We see this most in homes west of Santa Fe Drive where older masonry chimneys lack proper crown overhang. Our fix: full mechanical removal of the failed coating, NFPA 211 Level 2 camera verification of the substrate condition, then either reapplication with modified cure protocol or recommendation for stainless steel liner replacement if the tile base is too compromised.
- HeatShield UL-Listed factory-built chimney - lateral seam separation at offset angles. The UL-1777 listed chimney systems use a snap-lock seam design that can work loose where the flue makes an offset to avoid framing. In Littleton’s Columbine Knolls and Ken Caryl Ranch neighborhoods, we find this where installers routed around vaulted ceilings in 1980s-1990s construction. The fix isn’t more sealant; it’s section replacement with proper support bracketing, then a pressure-test to confirm draft integrity. We stock common HeatShield diameters and source through Haven’s buying network to keep lead times short.
- HeatShield ProLiner (stainless steel flexible liner) - premature corrosion at the rain cap interface. The ProLiner’s 316Ti alloy resists acid well, but if the original installer used a generic cap without proper condensate drainage, water pools at the top collar. Littleton’s spring snow loads and summer hail accelerate the rust point. We replace the damaged upper section with matching HeatShield spec or, if availability is tight, a DuraFlex 316Ti equivalent that maintains the UL listing. Corrine Halstead checks the cap geometry herself on ProLiner jobs - the wrong overhang dimension voids the warranty and starts the cycle again.
- HeatShield refractory panels (manufactured fireplace) - thermal shock cracking above 2,500 ft. elevation. Littleton sits at 5,400 feet, and the lower atmospheric pressure changes how factory-built fireplaces breathe. HeatShield’s refractory panels can develop hairline cracks within 3-5 seasons that don’t show until a Level 2 camera inspection. We measure the crack width and map it against the panel’s heat-exposure pattern. Repairable cracks get high-temp ceramic fill; anything through-panel gets OEM replacement with elevation-specific draft adjustment noted on the final report.
- Smoke chamber parging (HeatShield Chamber-Tech 2000) - slumping in oversized fireboxes. Chamber-Tech 2000 is rated to resurface corbelled smoke chambers, but when original builders in Littleton’s older subdivisions like Valley Heights oversized the firebox for ” ambiance,” the parging layer is too thin to handle thermal cycling. We remove the slumped material, re-profile with proper thickness per HeatShield’s engineering table, and document the before/after with camera footage. The camera doesn’t have an opinion - it just shows you what’s there.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24/7. We book your NFPA 211 Level 2 inspection with camera scan - included as standard, not an upsell.
- 2
Inspection and documentation. Your assigned, background-checked technician arrives in uniform with license information visible. We run the camera down the flue, record the footage, and mark readings for liner condition, draft performance, and clearance to combustibles.
- 3
Written price before work starts. Corrine reviews the footage and builds a scope with line-item pricing: parts (OEM HeatShield or quality aftermarket from Gelco or DuraFlex if availability or cost favors it), labor, and testing. You get the written price, written scope, and written warranty before anyone picks up a tool - Haven Standard Clause 1.
- 4
Repair with parts verification. We photograph every part label at delivery. HeatShield OEM when warranty requires it; DuraFlex or Gelco equivalent when the spec matches and the price is better for you. No substitutions without your signed approval.
- 5
Post-repair testing and documentation. Smoke test or pressure test depending on the system. Camera re-run to confirm the fix. Photos, footage, and readings compiled into your documented record - Haven Standard Clause 4, same as we’ve done since 2009.
- 6
Cleanup and guarantee. Work area vacuumed, drop cloths removed. Your 365-Day Done Right Promise is stamped on the invoice. If it’s not done right, we make it right.

Why Littleton Homeowners Call Level Two Chimney Littleton for HeatShield Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and HeatShield systems have been part of that mix since the brand gained traction in Colorado in the early 2010s. Our technicians know the difference between a Cerfractory delamination and a liner that needs full replacement - and we show you the camera footage so you can see it too.
The Haven Standard governs everything we do. Clause 4 requires that documented photo record on every visit. Clause 1 requires the written price before work starts. The 365-Day Done Right Promise covers the labor and materials. We’re independently owned and operated, not a franchise, and we source materials through Haven’s buying network specifically to keep customer prices honest - whether that’s HeatShield OEM, DuraFlex, or Gelco.
Corrine’s crew has worked throughout Littleton, including older homes in Columbine Knolls where masonry fireplaces still get heavy use through the long Front Range winters. When a HeatShield part is backordered, we have relationships with alternate suppliers so you’re not waiting all season.
FAQs
No, if the work is performed using OEM-spec parts and proper cure protocols - but HeatShield’s warranty does not cover labor, only materials. As an independent HeatShield service provider, we document every part serial number and installation condition so any future warranty claim has the paperwork it needs. Our 365-Day Done Right Promise covers our labor separately. Call (720) 439-4666 if you want us to review your existing warranty status before we start.
Most ProLiner or factory-built chimney replacements are completed in one day, with fire-testing possible by evening. Cerfractory resurfacing requires a 24-hour cure before the first fire, so we schedule those jobs when you can afford the downtime. We don’t rush cure times - Littleton’s dry climate helps, but we verify hardness before sign-off. Call (720) 439-4666 to book around your schedule.
We stock common HeatShield diameters and spec parts, and we source through Haven’s buying network for less common sizes. When HeatShield OEM is backordered or priced uncompetitively, we may recommend DuraFlex or Gelco equivalents that match the UL listing and material spec - but only with your written approval and full documentation of the substitution. The invoice notes exactly what was installed.
The camera decides. Hairline cracks in refractory panels or localized Cerfractory delamination often repair. Multiple joint failures, corrosion through the ProLiner wall, or any deformation of the flue path means replacement. We show you the footage, explain the readings, and give you both options when both exist. Nothing is recommended without camera evidence you can see for yourself. Call (720) 439-4666 for a free inspection and honest assessment.
A compromised flue liner allows heat, smoke, and carbon monoxide to reach combustible framing - the leading cause of chimney-related house fires. In Littleton’s dry climate, creosote buildup accelerates in a damaged flue because draft is impaired. That said, we tell you plainly when a condition can safely wait a season and when it can’t. The inspection report separates “monitor” from “act now” with the footage to back it up. Call (720) 439-4666 for the inspection; estimates are free.
